Why do tears and snot taste the same?
You haven't tried all the snot yet. They are different. And it tastes too.
Tears, snot, semen, urine - everything is based on blood plasma. Because of this fundamental principle, the taste of these liquids is not very different. More precisely, it is different, but everything is salty and tasty, as it can turn back into blood plasma (in the urine, however, there are excess unnecessary salts).
